A pup question,
Is it mandatory that we set up the BIND9 service?

Re: Problem receiving email from gmail or outlook
Ok. So if you tested from outside your network, by doing a "telnet host.domain.com 25" and you got the response from your postfix server, then we can discard public dns records or your perimetral network being the cuase of the issue.
So, when you do connect from the outside to your network via telnet, can you send an email then? Using the "ehlo" "mail from:" "rcpt to:" "data" typically used to test servers? (google send email via telnet if you are not familiar with this method). While you do that test, you could try to "tail -f /var/log/zimbra.log" so you see the connection and the mail send attempt. This log will tell you quite clearly what's failing.
Please perform that test (again, from outside of your network) and share the results from both the telnet session and your log.

Re: Problem receiving email from gmail or outlook
Not at all. Why would you even do that? What you could use is the embedded dnscache service that comes with zimbra. Then, just configure that service (via zmprov) to use your internal DNS servers as forwarders. Enable that dnscache service only on your MTAs servers.Is it mandatory that we set up the BIND9 service?
Usually, everybody has an already working DNS server in their organization, deployin a new one just for Zimbra is just wrong.
Re: Problem receiving email from gmail or outlook
yes I did a test from the old network by doing the command: telnet host.domain.com 25 and I got this result:pup_seba wrote:Ok.

user @ host: ~ $ telnet host.domain.com 25
Try @ip_server ...
Connected to host.domain.com.
The escape character is '^]'.
220-host.domain.com ESMTP Postfix
220 host.domain.com ESMTP Postfix
When I send a mail from:
"zimbra" sends mail to "gmail or others" "result: well received"
but if "gmail" answers "zimbra" "result: message sent" and if I check on zimbra it does not happen. I do not know if you understood me.

Re: Problem receiving email from gmail or outlook
Hi,
No sorry, I don't understand your explanaitions. I also don't understand what implications testing from an "old network" may have or if that is truly the equivalent to testing from outside your network (can't be that hard).
Regarding this "Please perform that test (again, from outside of your network) and share the results from both the telnet session and your log.", what are the results, for instance, this is what happens if I do it to my network:
· telnet host.domain.cat 25
Trying 8x.7x.1xx.2xx...
Connected to host.domain.cat.
Escape character is '^]'.
220-host.domain.cat
ehlo somehostname
220 host.domain.cat
250-zimbramta01.essi.lab
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
mail from:someone@somedomain.com
250 2.1.0 Ok
rcpt to:sebas@domain.cat
250 2.1.5 Ok
data
354 End data with <CR><LF>.<CR><LF>
This is a test.
.
250 2.0.0 Ok: queued as 03E561840DE1
In this test you can see how from outside my network I am able to resolve the hostname and connect to the 25 port. You can also see that the response is the one I expected and then I am able to send an email, at least at the mta level it is able to put it in queue. This should be the point we are on based on your confirmation that you can perform these tests. The logs generated by this test under /var/log/zimbra.log (the ones I asked) are the ones that will show you what's wrong.
I dont fully understand why you add comments about test from your Zimbra to gmail...are they also not working or something? I thought that only receiving the emails from outside your organization was not working.

Re: Problem receiving email from gmail or outlook
Hi,
I did the test in another network and the result I got was just:
$ telnet host.domain.com 25
Try 1xx.5x.1x.xx ...
Connected to host.domain.com.
The escape character is '^]'.
220-host.domain.com ESMTP Postfix
220 host.domain.com ESMTP Postfix
421 4.4.2 host.domain.com Error: Timeout exceeded
Loss of connection to the host.
i have done all the checks i think and you have below the log for further analysis.
Actually zimbra test to Gmail works well. it's just to receive the answer from Gmail that does not work.
Thanks

I did the test in another network and the result I got was just:
$ telnet host.domain.com 25
Try 1xx.5x.1x.xx ...
Connected to host.domain.com.
The escape character is '^]'.
220-host.domain.com ESMTP Postfix
220 host.domain.com ESMTP Postfix
421 4.4.2 host.domain.com Error: Timeout exceeded
Loss of connection to the host.
i have done all the checks i think and you have below the log for further analysis.
Actually zimbra test to Gmail works well. it's just to receive the answer from Gmail that does not work.
Thanks

Re: Problem receiving email from gmail or outlook
So the tests from the outside are not successful.
Do you have your Zimbra firewalls enabled at an OS level? How many zimbra servers do you have? Are they on the same network?
Does this error "421 4.4.2 host.domain.com Error: Timeout exceeded" happens right away? I mean, do you even have the chance to type the "ehlo" command?

yes we can say that it does not work. Can you give me the correct DNS configuration to see?
I have one zimbra server in the cloud and it's not in the same network, it's in a public network
Can you send me a zimbra installation documentation complete with the dns and other prerequisites to compare what I did if there was no error.
thank you

Re: Problem receiving email from gmail or outlook
You didn't answer the question that's been asked about a firewall? Is it enabled and if so, set-up a Split DNS configuration. Documentation for Zimbra is on the Zimbra web site, there's also a ton of posts in the forums and wiki articles on how to configure DNS records, it is assumed that you'd know how to configure those if you're running a mail server.
